One day two psychiatrists were walking along a river in Liverpool when they noticed a scouser floating along in a boat singing, "Row, Row, Row your boat, gently down the stream......."They instantly decided that he was crazy so they grabbed him, took him into hospital and removed 1/4 of his brain.A few days later they again saw the scouser in his boat singing "Row, Row, Row your boat........"Again they grabbed him, took him to hospital and removed another quarter of his brain.A few days later they again saw the scouser in his boat singing "Row, Row, Row your boat........". Again they grabbed him, took him to hospital and removed another quarter of his brain.A few days later they again saw the scouser in his boat singing "Row, Row, Row your boat." This time they took him away and decided that the best thing would be to remove all of the rest of his brain.A few days later they again saw the scouser in his boat singing "Ferry, on the Mersey.........."
